SAW-OILER.

Patented July 29, 1919.

Application led December 29, 1917, Serial No. 209,554. Renewed December 28, 1918. Serial No. 268,707.

This invention relates to new and useful improvements in saw oilers, and the principal obj eet of the invention is to locate an oil container in the handle of a saw and to provide means for delivering the oil to the blade of the saw at will.

Another object of the invention is to provide means whereby the device may be adjusted to suit different sizes of saws.

Another object of the invention is to provide a device of this .character which is simple and durable in construction, reliable and efficient in operation and one which can be manufactured and placed upon the market at a minimum cost.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation showing the invention applied to a saw.

Fig. 2 .is a section on line 2 2 of Fig. 1.

Fig. 3 is an enlarged section on line 3 3 of Fig. 2. e

As shown in these figures the invention is applied to the saw handle A which is of ordinary construction and is connected with the blade B in the usual manner. An opening is made in the handle and blade of the saw adjacent the inner edge of the handle, to receive the oil container 1. This container is preferably of cylindrical form and is provided with a flange 1 and a screw cover 2 which is also provided with a flange 2. The flanges 1 and 2 are adapted to engage the faces of the handle, and due to the screwthreaded connection of the cover with the container, said container may be adjusted to suit different thicknesses of saw handles. An inclined opening is made in the handle and extends from the upper edge thereof to the lower edge to one side of the center so as to place said opening to one side of the saw blade. This opening is to receive the inlet tube 3 and the outlet tube 4. The outer ends of these tubes are provided with notches to receive a screw driver or the like and the inner ends of said tubes are screw threaded to engage with the screw threaded openings in the container. The container is reinforced around said openings as at 5 so as to secure a tight connection between the container and the tubes. The outlet tube 4 extends from the container through the lower end of the opening and slightly projects therefrom, as shown. The inlet tube 3 has its lower end extending well into the container to a point slightly above the inner end of the outlet tube. This end is reamed out to provide a shoulder 6 to form a seat for the end of the coil spring 7 which tends to hold the valve 8 on its seat 8 formed in the inner end of the outlet tube. The outer end of the valve 8 is semi-circular in form as shown. The outer end of said inlet tube projects slightly above the edge of the handle and I prefer to form the hole for said tube Within the recess A usually formed in the' saw handle. 9 represents the clip secured in the recess A to which is pivoted a lever 10 having one end bent up to form a finger engaging part and its other end provided with a lug 11 to which is connected a wire 12 having its other end connected with the valve. This wire, as will be seen, passes through the inlet tube and through the spring 7 and is connected to a lug 13 formed on the valve. I prefer to form a spring section 14 in said wire. The parts are so arranged that the spring 7 will hold the valve on its seat with the lever 10 in its lower position but when said lever is raised the wire 12 will lift the valve off' its seat t0 permit the flow of oil through the outlet tube. The lever 10 in its normal position will cover the outer end of the inlet tube. This inlet tube is provided with an opening l5 at a point adjacent the upper portion of the container for permitting the container to be filled with oil through said tube. When the container is to be filled the lower end of the outlet tube is closed in any suitable manner and then the lever 10 is raised and the oil poured into the tube 3. The oil will flow through said tube, through the opening 15 and thus fill the container.

It will be seen that when the saw is being used and it is desired to oil the blade the lever 10 is operated by the fore-finger. rlhis will raise the valve and the .oil will HOW from the container into the outlet tulbe, and from this tube Will drop on to the blade.

By Vplacing a considerable number of threads inthe container and on the endlsoi the tubes it Will be seen vthat the device may p YVhat I claim is:- A sawciler comprisingarcontainer located lin the saw handle and provided with flanges engaging `said handle, an inlet tube extending through saidxr handle and having its .lower end .extending into and adjustably Vconnected with the container, an outlet tube v-adjustaloly connected With the feontaine-r, a

valve located in saidv inlet tube, a spring 'in said tube for normally holdingsaid valve with 'its end closing the outlet rtube, alever and a lconnection includingfa spring i:passingV through 'the Yinlet YLtube 'and =connecting the valve With the lever. l

Iii-testimony whereof I aiX my signature.
